MILLING HEADS AND ACCESSORY.

The range of big-sized vertical lathes VERTIGO represents the new reference point of the sector.
FPT decade-long planning and technological experience in manufacturing big-sized hydrostatic borig machines , finds a new implementation in the turning, milling and grinding technology of big mechanical components.
The result is a new family of machines offering solutions available for the first time on the market:

- Full hydrostatic movement of all axes (included the vertical movement of the beam W) with “active” oil cooling system;
- Clever hydrostatic thrust-bearing “tilter” for the table bearing and rotation with automatic unbalancing control of the loads to be machined, with adjustment data self-learning (Patent Int. Pend.);
- “Load control” device allowing constant maintenance of the geometry and stiffness of the table according to the loading condition changes, by means of a hydrostatic system with “active” preload (Patent Int. Pend.);
- Turning spindle movement transmission device with hybrid gearbox (planetary+parallel) and high torque and liquid-cooled built-in motor;
- Dual Drive type, dedicated high stiff transmission system of C axis with complete backlash compensation and with very high bidirectional dynamics (deriving from the big-sized table of FPT boring machines);
- Direct Drive kinematic system of the milling spindle. This solution manufactured for years by FPT for its boring machines, provides an in-axis power transmission to the spindle, without mechanical gear systems, through high torque liquid-cooled built-in motor. The advantages are certain in terms of stiffness and kinematic efficiency, with cancellation of wear and heating of the mechanical parts and subsequent optimization of milling accuracy;
- X axis movement (saddle-ram movement) with double pinion, rack and Dual –Drive management. It allows an improvement of the stiffness and accuracy performances achieving results that cannot be compared with the traditional screw transmission;
- Active compensation of the machine geometry able to maintain the constant trim of the structures in all positions of the moving masses in the working field.

SPIRIT, the hydrostatic boring machine series, incorporates the essence of FPT and expresses its great potential in terms of innovation. FPT summarizes in SPIRIT its experience of the big hydrostatic machines designed and installed throughout the world during these last decades, succeeding once again in setting a new base line in this field.
SPIRIT boring machines are equipped with a ram completely closed on four sides that slides inside a perfectly closed saddle which wraps around the ram itself. A perfect solution in terms of rigidity and symmetry.

In the field of boring machines, FPT CASTEL undoubtedly represented the reference point on an International scale for the innovation in the last few years both under the design concept and under the structural profile.
Once again these elements made of this machine another extraordinary object of FPT company, having no equals in the market of its category.
CASTEL has been conceived from the beginning according to revolutionary criteria and design. It is characterised by a unique column structure integrating the longitudinal sliding saddle.

Thanks to its dynamic performance and versatility, STINGER can be used in the working of moulds and dies in both the pattern and mechanical parts, in the machining of 5 faces and inclined surfaces, and in aeronautical working. The machine is conceived with one rotation axis on the head with universal geometry and one on the rotary table. This original solution provides an extraordinarily large useful work field in comparison with the travel of the axes. The head is drawn on the patented solution already applied on Dino machine that permits undercut working and has a negative “pivot” allowing the use of the ram vertical travel at best.
